New rig, toasty proc with a BSOD

[Joeydubbs]

I built the rig in the sig over the weekend without incident. I was playing starcraft 2 and got an error message "whae uncorrectable error" which forced a restart. This only happened once but got me to investigate...

I ran prime 95 and saw cpu temps in the upper 90's, is this normal? I didn't let it run long as these temps scared me...no error message however

Using stock settings and stock cooler...can someone comment if this is right? 90's seem high...

 

[ShintaiDK]

Assume stock.

90C is fine under prime95. The CPU will start throttle at 100C. Intel garantees it will work at tjmax (100C) for 3 years straight at stock conditions.

 

[Joeydubbs]

ok thanks, not sure what to make of my bsod experience, hopefully an isolated experience. If it happens again I guess ill test memory etc...

btw, if I get an aftermarket cooler, how do I (or should I) remove the thermal compound from the stock cooler/proc?

 

[Schmide]

He said upper 90s. Considering there is some variation in tj.max there is a good chance it has started throttling. Once it hits the wall it will throttle and you will see temps drop below the tj.max. I'd check that cooler's mounting.

 

[spat55]

Yes, I would check the cooler and see if it is mounted correctly, the stock coolers I have heard are easy to make mistakes fitting.

 

[GreenChile]

There's no way it should get that hot with stock settings, even with the stock cooler. The most likely cause is a bad mounting of the CPU cooler.

 

[BallaTheFeared]

Either way he shouldn't get a 124 error, check to make sure the chip is running stock and its not being overclocked by the board.

 

[Joeydubbs]

Ill check the cooler, the pins snapped down nice and firm but maybe there isn't good contact...

CPU idles around 40C, during SC was getting around 70C the last I checked, but prime95 just cooks it...

 

[AtenRa]

Maybe the ASUS board overclocks ALL Cores to 3.9GHz at stock settings, combine that with stock cooler and temps will skyrocket.

I would check the BIOS settings first (look at the CPU Turbo settings) and then i would check the Cooler mounting.

The 4770K cannot handle Prime95. Just forget it. Its a very stressed CPU when having high loads(esp. AVX). Mine will throttle with Prime95.

Yep, the setting is most likely something called Multicore Enchancement.

Prime95 and 4770K(+big cooler with NB fans)

In contrast to the 8350 thermal design......the 4770K is horrible. And this for 292 euro!!!

Is a 3.5Ghz uncore default?

Your voltage also looks high. Never seen mine pass 1.1V with AVX2.

Must be a big difference, since my 4670 with the tiny stock cooler doesnt throttle.

So if your 4770K throttles with stock cooler and correctly seated and running all values at stock, including VID. Then you should simply RMA your CPU and get a new.

Just go to a drug store and buy some isopropyl alcohol. It comes in several different concentrations ranging from 70-99%. If you can find 99% it's better as there is less water in it but the others work just as fine (you don't need to spend a lot of money on exotic cleaners). Soak a paper towel with it and just wipe the thermal compound off. You might need to do this several times to get it all off. You can use a soaked Q-Tip to get compound off around the edges. Surface of the CPU should be absolutely clean before you mount a new heat sink.

At 3,5 GHz core freq it does not throttle.........just.
If you look at my i3-4130 thats even worse. With Prime95 it throttles................and is not OCable. Haswell thermal design is a disaster.

If you are sure everything is at stock, including voltage, then RMA it.

Mine doesnt throttle. Not even at 175Gflops in Linpack.

Could you do me 1 favour............to load it with prime95(FPU mode) and look with the Intel prog. XTU what the temps are. Thanx()
It would give me an id of the actual differences and if I have to RMA it. When I have the 4770K on default, core freq. 3.5Ghz, it will get to 88C with a big cooler(@3.7Ghz it will throttle). The 4130 gets to throttling anyway with Prime95 and everything at default.

XTU doesnt work well on my PC. As the 7Ghz screenshot already showed.

Nor Prime95 or Linpack 11 will make it throttle.

But to what temps does it get?

 

[ShintaiDK]

But to what temps does it get?

Highest core 93C. 1.088V. 3.6Ghz turbo. And for Linpack 11, ~175Gflops.

3570K peaks at 88C in the same loads and 1.096V. But only ~102Gflops.

If your CPU throttles below stock frequency(not turbo), then RMA it and get a new one.

Thanx:thumbsup: could you give me the name of the file u use to test your cpu with linpack 11, there are several files in linpack 11.

If you dont want the textfile output. And run x64.

Open a CMD. Go to \linpack_11.1.0\benchmarks\linpack

Type this:
set KMP_AFFINITY=nowarnings,compact,granularity=fine
set PATH=..\..\..\redist\intel64\compiler;%PATH%
linpack_xeon64.exe lininput_xeon64

Optional for amount of threads you can use: set OMP_NUM_THREADS=(number of threads). default is all threads supported.

Else simply run the runme_xeon64 batchfile and look in the win_xeon64 textfile for output.

:thumbsup:thx
PS how long should I run it. Gflops is 87 now. It looks(in XTU) like it is just using 2 cores.

Tested the 4770K.....no HT............ with Prime95(in FPU test mode)
1. @stock(=3,5Ghz) is 74C@1.0880V Vcore.
2. @3,7Ghz is 85C@1.1670V
With HT
1. 88C@1.0880V
2. >100C@1.1670V............bringing this down 100mv gives a max temp of 86C

I noticed in XTU that you can adjust Dynamic CPU Voltage Offset, what is a good stresstest to give this a negative value? I tried -100mv and Prime95 @3.7Ghz. That went OK.
Update: -100mv was too much, it crashed after a while.

Thanks for the replies everyone. I wanted to give an update...

The stock cooler appears to be seated correctly. I had a nice gaming session of AC4 and my proc never got higher than low-mid 60's, haven't gotten a bsod error again either so maybe (hopefully) that was a fluke

As mentioned in this thread, it appears that the 4770k with HT just can't handle prime95 with stock cooling. I can't decide if a need an after market cooler now...
